问题 I have no experience with JOptionpane but I need a simple program to simplify my life. The code I need help with is below: public static void main (String[] args) { String input = ""; input = JOptionPane.showInputDialog("Enter code"); JOptionPane.showMessageDialog(null, toStringU(toArray(input)), "RESULT", JOptionPane.INFORMATION_MESSAGE); } toStringU method gives me a long long text I want to run it without any compiler (a standalone application, double click, put info and take results). And

I am trying to make a JOptionPane get an input and assign it to an int but I am getting some problems with the variable types. I am trying something like this: Int ans = (Integer) JOptionPane.showInputDialog(frame, "Text", JOptionPane.INFORMATION_MESSAGE, null, null, "[sample text to help input]"); But I am getting: Exception in thread "main" java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Integer Which sounds logical yet, I cannot think of another way to make this happen. Thanks in advance Simply use: int ans = Integer.parseInt( JOptionPane.showInputDialog(frame,

How to change the button backgrounds inside JOptionPane

由 落爺英雄遲暮 提交于 2019-11-30 07:41:39
I was wondering if anybody knew if it was possible to change the background color on the buttons inside a JOptionPane . I know how to change the entire JOptionPane background using a UIManager , but know what I want is to set the individual okButton, cancelButton, and so on within the JOptionPane to separate individual colors. If I can do this, how would I do this? Thanks for the help. There is no direct way to do this. But if you really want to give it a try, then you will need to read the JOptionPane API which gives code that shows you how to manually create and display a JOptionPane without

问题 I'm trying to get the PayPal logo come up when you click the 'rightbutton' is clicked. Unfortunately, all that shows is the default Java logo with the cup of coffee and a pen. Also, how can I make it so once you click "OK" or "Cancel" it closes the JOptionPane, currently, when you click "OK" nothing happens, it keeps giving you the "OK" / "Cancel" option. rightbutton = new JButton("Right."); add(rightbutton); rightbutton.addActionListener( new ActionListener(){ public void actionPerformed

问题 So, I've read the Java API, but still can't seem to make heads or tails about how to do this. And believe me I have tried. I want an ActionListener to cause a message box with the text 'Do you really want to exit?', with options yes and no which exits the program or not depending on the selected button. Here's what I have for the ActionListener before I started to break it with the message box: exitItem.addActionListener( new ActionListener() { public void actionPerformed(ActionEvent arg0) {

Edit: The question follows the horizontal rule; my own answer precedes it. Based on help from Oscar Reyes , I crafted this solution: import javax.swing.JOptionPane; import javax.swing.JFrame; public class MyApp extends JFrame { public static void main(String [] args) { new MyApp(); } public MyApp() { super("MyApp"); setUndecorated(true); setVisible(true); setLocationRelativeTo(null); String i = JOptionPane.showInputDialog(this, "Enter your name:", getTitle(), JOptionPane.QUESTION_MESSAGE); if(null != i) { JOptionPane.showInputDialog(this, "Your name is:", getTitle(), JOptionPane.INFORMATION

问题 Can you change the font and size of the text of a JOptionPane? I tried it and it works only if I "run file" on that specific java class. If you start the whole project it does not change the font. I only want to change only a specific JOptionPane not all of them. Here is the code: UIManager.put("OptionPane.messageFont", new FontUIResource(new Font( "Arial", Font.BOLD, 18))); JOptionPane.showMessageDialog(null,"MESSAGE","ERROR",JOptionPane.WARNING_MESSAGE); 回答1: It's really easy.
